and then yet another group of immigrants began to pour in. ( children shouting ) this group came from brazil's. between 1955 and 1980, more than five millionrrived, attracted by the promise of work ana better life. but an already crowded city could not absorb them. so they began to build tir own homes and neighborhoods, but an already crowded city brick by brick, couon the periphery.m. this so-called "self-construction" caused the city to spread even farther. translator: the gigantic size of sao paulo, ( scarlato speaking portuguese ) in a horizontal see, is aesult of self-construction. in a chaotic, disorganized way, without planning, it spoaneousen e in all direcons. rrator: today, saoaulo h swelled toncompass over 3,000 square miles,

dbumany othe most importantt sos new roads intohe intiorepresents still dirt and not paved. paving greatly accelerates the change. nepstad: and what we're going to do is just look a little bit into the fute, imagining th these roads, which are still dirt roads, are all paved, as is slated by the federal government of brazil. narrator: in this simulation, the growing red area represents new deforestation every two years up to the year 2020. so as these roads are paved, deforestation is basically going to march up along those roads. instead of all the deforestation being concentrated along theast and south, we've made inroads into the core of the basin. narrator: at the southern edge of that core, a new economic force is pushing the pavement north.

from space, we see fields of soybeans etched in the shrinking forest. brazil is about to overtake the u.s. as the world's leading producer of soy, exporting their crop to millions of chinese consumers and european livestock growers. the soy farmers of mato grosso are very keen on having asphalt so that they can ship their soybeans to the santarém port and puit on oceangoing freighte and serve the world markets that way. it's much cheaper that way than to go south to the big brazilian ports down south. as that pavement goes through, the ancillary effect of paving, of course, will be to make it cheaper for everyone to do business along that corridor. but let's just imagine for a second two different trajectories for this road. he we see the portion that's not yet been paved-- santarém up here, mato grosso down here. in a business-as-usual situation, as paving goes in here, people will move in along the highways,

driven largely by land speculation interests, putting cattle pastures, shifting cultivation. and we can see the deforestation frontier rapidly eanding along this road. but there is reason to think that another scenario is possible. narrator: the lower rates of deforestation are based overnmen ctrcin the environmental laws on the books. brazil has received some help from some new technology and from other ecologists, including chris uhl. uhl is the founder of imazon, a research institute located in the city of belém. the law in pará state says that 50% of all prate land must be maintained in forest. until recently, that was very hd to monitor. now, using a system of satellites casearcher carlos sousaiing cadot,

set by farmers during the dry season to release the nutrients from the vegetation. but the soil's producvity disappears,n sometimes in one or two years. it forces settlers to abandon their land and cut more forest elsewhere. because this requires more land all the time, it is a form of extensive agriculture. it's called "shifting," "swidden" it's pcticed inany ngs or "slash-and-burn" cultivatio until the forest runs out. this land waabandonedby sgs a few years earlier. the sight of new trees led chris uhl to a surprising and controversial revelation. l: whenirststted wog wn , i really thought that the las were extrely fragile wasn'a ssse,t was abdoor sture l: whenirststted wog wn , and yet, if u look over he i woulveueed that ts ece of land

11:25 am
( speaking portuguese ) translator: because grazing was degrading my fields, the farm didn't have a means to produce new grass. ( continuing in portuguese ) so, i decided to research what i'd seen done in other places and i intensified my planting. of course, there was an initial cost, but the return has been good, and it's paying for itself. narrator: these practices work well on a small scale in the eastern amazon, but can they be used throughout amazonia? this remains to be seen. the first results of this research showed that we have aroun 50% to 60% of the state apopriate for loggg. that we have aroun and whene put together... state narrator: imazon has determined that, overall, about 20% of pará state's land area
